Sizes and screens
A module brings its own layout for every screen size and keeps it wherever it runs.
Four layouts
Every module has a layout for desktop, notebook, tablet and mobile, made for widths of 1240, 1024, 778 and 480 pixels by default. Change these breakpoints for your account under Settings, Advanced.
No jumping
The module's height and background are set before anything else loads, so the text around it stays where it is while the module arrives.
Changing a size
In Quick Edit, type and colour follow desktop until you change them for a size, and a layer can be hidden on a size. The layout itself stays as designed.
